Genetron® AZ-20 (R-410A) Description
Genetron AZ-20 (an azeotropic blend of HFC-32/HFC-125) has been created to serve as a long-term, non-ozone-depleting substitute for HCFC-22 in a range of modern equipment applications.
It has a low inherent toxicity and much higher pressure and capacity than HCFC-22. It is simple to service in the field because of how it operates like an azeotrope.
